Elon Musk: Solar energy is the key to fixing Puerto Rico's power grid

"The Tesla team has [built solar grids] for many smaller islands around the world, but there is no scalability limit, so it can be done for Puerto Rico too," Musk tweeted Thursday. "Such a decision would be in the hands of the PR govt, PUC, any commercial stakeholders and, most importantly, the people of PR."

Any Tesla solution would be aimed more towards the long-term, rather than the immediate restoration of power that is desperately needed, though.
